2014-02-05drm/vmwgfx: Reemit context bindings when necessary v2Thomas Hellstrom
When a context is first referenced in the command stream, make sure that all scrubbed (as a result of eviction) bindings are re-emitted. Also make sure that all bound resources are put on the resource validate list. This is needed for legacy emulation, since legacy user-space drivers will typically not re-emit shader bindings. It also removes the requirement for user-space drivers to re-emit render-target- and texture bindings. Makes suspend and hibernate now also work with legacy user-space drivers on guest-backed devices. v2: Don't rebind on legacy devices.

2013-12-04drm/vmwgfx: Fix dma buffer memory size accountingThomas Hellstrom
Also request kernel ttm_buffer objects for buffer objects that obviously aren't visible to user-space, and save some device address space. The accounting was broken in a couple of ways: 1) We did not differentiate between user dma buffers and kernel dma buffers. 2) The ttm_bo_acc_size function is broken in that it a) Doesn't take into account the size of the optional dma address array, b) Doesn't take into account the fact that drivers typically embed the ttm_tt structure. This needs to be fixed in ttm, but meanwhile provide a vmwgfx-specific function to do the job.

2013-08-19drm/vmwgfx: remove ->firstopen callbackDaniel Vetter
So if we survey kms drivers there's a bunch of things they commonly do in ->lastclose - delayed processing of vga switcheroo requests (i915, nouveau, radeon) - force-restoring the fbcon (most) - resetting a bunch properties to make fbcon work better (omap) - disabling all outputs (vmwgfx) In short besides the semantically important vga switcheroo stuff they all try very hard to keep fbcon working in case X dies. But none of them try to not do this at driver unload time safe for vmwgfx, and digging through logs I couldn't find any reason for why vmwgfx is special. Since ->firstopen has lots of potential for abuse with kms drivers (like delaying driver setup to pamper over races in the load sequence) it's imo very much worth it to remove this logic so that we can stop using the ->firstopen callback for kms drivers. Also module unloading is rather a debug feature and developers should know how to restore the display to a sane configuration.

2011-10-05vmwgfx: Fix up query processingThomas Hellstrom
Previously, query results could be placed in any buffer object, but since we didn't allow pinned buffer objects, query results could be written when that buffer was evicted, corrupting data in other buffers. Now, require that buffers holding query results are no more than two pages large, and allow one single pinned such buffer. When the command submission code encounters query result structures in other buffers, the queries in the pinned buffer will be finished using a query barrier for the last hardware context using the buffer. Also if the command submission code detects that a new hardware context is used for queries, all queries of the previous hardware context is also flushed. Currently we use waiting for a no-op occlusion query as a query barrier for a specific context. The query buffer is also flushed and unpinned on context destructions, master drops and before scanout bo placement.
